Increase of artifacts for Archy in 4.3?

So I was on the PTR killing time between ques for testing and was working on my Arch. I noticed instead of only 2-4 artifacts per dig I was getting between 5-9 artifacts per dig. Is this an undocumented increase for 4.3 or was this a change made awhile ago?

Yeah so hoping this isn't just some kinda bug they haven't caught yet. Wish there was a way we can get the higher ups here on MMO champ to let us know if that is something in the datamined info for the patch.

If this is true I will be so happy. I have been trying to get the crawling hand pet from Uldum for such a long time. Soooo many Night Elf digs. Never the rare Doll proc so I can finally be done with the Night Elf rares. I would love more fragments!
